Abstract: Geophysical investigation using electrical sounding technique was carried out in Tanke community Ilorin, in order to characterize or explore ground water potential. The top soil resistivity values vary from 68.1Ωm to 65.1Ωm and thickness varying between 1.7m to 9.9m. The second layer resistivity values varies from 32.9Ωm to 651.1Ωm and the thickness vary from 2.9m to 12.7m.The third layer is the weathered basement with resistivity and thickness values varying between 22.6Ωm to 9562.6Ωm and 7.8m to 51.1m.The fourth layer is the partly weathered and fractured basement with resistivity and thickness values varying between 101Ωm to 2100Ωm and 80.1m to 124m while the fifth layer is apparently fresh basement whose resistivity values vary from 154.9Ωm to 7130Ωm with an infinite depth. The study further reveal VES 3, 4, and 5 as productive fractures within the weathered basement while other VES points are not productive.
